In a heartfelt episode of his YouTube series 'The Trews', Brand, 42, said what Sinead needs, "like anyone else suffering with mental health issues needs, is connection, meaning, purpose, love and a bit of time, really".

Responding to the actor, writer and funnyman on Facebook, Sinead said: "Thank you so much for your beautiful support. Have always felt a great kinship with you.

"Could also do with a jolly good rogering, frankly. The last man who touched my body took out my reproductive system two years ago.

'So if you really wanna be part of my healing journey, c'mon, horse it into me, boss."

In a later post, she added: "In case of a long line forming... its only Russell I wanna do, so don't waste your time."

In 2009 dad-of-one Brand, who was then dating Katy Perry, confessed he had a crush on shaven-headed Sinead.

"One always speculates what it would be like to be in a romance with dear Sinead," he told the Sunday Independent.

"That would be exciting wouldn't it? I have never met her and I don't think I'd approach her but I would definitely await an introduction."

But it seems Sinead has missed the boat as serial womaniser Brand is set to get married again this month – this time to long-term girlfriend Laura Gallacher.

The pair welcomed their daughter Mabel into the world last November.

Meanwhile, mum-of-four Sinead, 50, who became a grandmother in 2015, has been keeping fans up to date with her recovery and revealed she is going on a relaxing holiday.

She said: "Being the lucky girl I am, someone who loves me has offered to bring me on a very nice holiday. (Russell can visit though) and there won't be any internet.

"So I will be off radar for a few weeks but didn't want you all worrying so thought best let you know."
